Yes I saw you can open database but your problem is on sort did you use of debugger for see detaily
|
|
|
|

Yes WhiteSky, i used the debugger and saw detaily.. When the control comes to the line, record -> Open(CRecordset::snapshot, "Pin_List"); it goes into the CRecordset::Open function and when it reaches the line BuildSQL() line it goes into that function, and then when it reaches the line BuildSelectSQL() line it goes into it . In that BuildSelectSQL() function, there is a line ASSERT(m_nFields!=0); When the control reaches this line, it displaying the Abort message box.. Its telling that the error is in the file dbCore.cpp and in the line 3282. You please analyse this. Or please suggest me some other way, WhiteSky.. Thank You.
With Regards,
Sangeetha.

That assertion error is happening since the m_nFields value is 0. The excel sheet have been created already. I didnt know how come the no of fields value equals zero.

Whitesky,
I go through the link referred by you, and tried as following,
void CPinListGeneratorDlg::ExcelOutPut()
{
CFileDialog MyFileDialog( FALSE, _T("xls"), NULL, OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY, _T("Access Files (*.xls)|*.xls|(*.xls)|*.xls|all files(*.*)|*.xls||"),this);
MyFileDialog.m_ofn.lpstrTitle = "Save As";
if(MyFileDialog.DoModal() == IDOK)
{
FileName = MyFileDialog.GetPathName();
}
CDatabase database;
CString sDriver = "MICROSOFT EXCEL DRIVER (*.XLS)"; // exactly the same name as in the ODBC-Manager
CString sExcelFile = FileName;
CStr
ing sSql;
CString str1;
TRY
{
// Build the creation string for access without DSN
sSql.Format("DRIVER={%s};DSN='';FIRSTROWHASNAMES=1;READONLY=FALSE;CREATE_DB=\"%s\";DBQ=%s", sDriver,sExcelFile,sExcelFile);
// Create the database (i.e. Excel sheet)
if( database.OpenEx(sSql,CDatabase::noOdbcDialog) )
{
// Create table structure
float j;
CPinListSet1* recset;
recset = new CPinListSet1(&database);
recset->Open(NULL,NULL,NULL,"'TABLE','SYSTEM TABLE'",CRecordset::snapshot);
CString TableName, sSql;
TableName = "\0";
if(!recset -> IsEOF())
{
recset->MoveFirst();
while(!recset->IsEOF())
{
TableName = "[" + recset->m_strTableName + "]";
recset->MoveNext();
}
}
recset->Close();
if(TableName == "[Pin_List]")
{
sSql = "DROP TABLE Pin_List";
database.ExecuteSQL(sSql);
}
sSql = "CREATE TABLE Pin_List (NET_NAME TEXT,DUT_PIN TEXT,TESTER_CHANNEL TEXT,TRACE_LENGTH float)";
database.ExecuteSQL(sSql);
int ResultSize = aResult_Array.GetSize();
for(int i = 0; i < ResultSize; i++)
{
CResult* Result = (CResult*) aResult_Array.GetAt(i);
// Insert data
CString Sql("INSERT INTO Pin_List (NET_NAME,DUT_PIN,TESTER_CHANNEL,TRACE_LENGTH) VALUES (");
Sql = Sql;
str1 = Result -> NetName;
Sql = Sql + "'" + str1 + "',";
str1 = Result -> DutName;
Sql = Sql + "'" + str1 + "',";
str1 = Result -> TesterName;
if( (ExportUnit == INCH) || (ExportUnit == MM) )
Sql = Sql + "'" + str1 + "'," + "%.4f)";
else
Sql = Sql + "'" + str1 + "'," + "%.2f)";
j = (float) (Result -> TraceLength * Factor);
sSql.Format(Sql,j);
database.ExecuteSQL(sSql);
}
}
// Close database
if(database.IsOpen())
database.Close();
}
CATCH_ALL(e)
{
TRACE1("Driver not installed: %s",sDriver);
}
END_CATCH_ALL;
sSql.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s", sDriver, sExcelFile);
TRY
{
// Open the database using the former created pseudo DSN
database.Open(NULL, false, false, sSql);
// Allocate the recordset
// Allocate the recordset
CRecordset record(&database);
// Build the SQL string
// Remember to name a section of data in the Excel sheet using
// "Insert->Names" to be able to work with the data like you would
// with a table in a "real" database. There may be more than one table
// contained in a worksheet.
sSql = "SELECT NET_NAME, DUT_PIN, TESTER_CHANNEL, TRACE_LENGTH "
"FROM Pin_List "
"ORDER BY DUT_PIN";
// Execute that query (implicitly by opening the recordset)
record.Open(CRecordset::snapshot, sSql);
database.Close();
}
CATCH(CDBException, e)
{
// A database exception occured. Pop out the details...
AfxMessageBox("Database error: " + e->m_strError);
}
END_CATCH;
}
Am getting the error message "No columns were bound to prior calling SQLFetchScroll/SQLExtendedFetch".

I think your problem maybe of excel file if you run this example it work did you try this article with itself example?I think in your excel file you you have row and col but do you have table in this file.
|
|
|
|
|
Whitesky,
You please once again go through my Coding.. In that, i have created a table using the SQL Query "CREATE TABLE".. As well as i opened the Excel File created through my project and check with that.. I went to the Menu "Insert -- Name -- Define" and go through it.. There is a table created by the name "Pin_List", which representing all the rows and columns that are created..
Sorry for you troubling you again,
Sorry..
With Regards,
Sangeetha.

I think "Insert -- Name -- Define" on excel is for grouping,Right?I suggest on the excel see Menu Data->Table or Data-PivotTable.I guess your problem is in excel file excel if you saw previous link on excel file he declare columns with Table name.
|
|
|
|

Whitesky,
Even in there exe, the sorted result is coming only in the listbox of the dialog. And it is not getting updated in that "Readexcel.xls" file.. You please run that exe and check it out.
With Regards,
Sangeetha.
|
|
|
|
|
yes I saw did you see excel file in this project its strucutre is same with your excel
|
|
|
|
|
Yes.. But they are sorting the file that is created already.. But in my case, in that function am creating the excel file.. then i need to sort..
With Regards,
Sangeetha.

Is it correct? (1)you have a excel file(you have items and also table on it)(2)you can open this file(3)you can read of it(4)but you can sort items (or better you get runtime error) if you dont use of m_recordset.m_strSort what happens it work or doesnt work
|
|
|
|
|
Whitesky,
Now am very much confused. Is it possible to see the sorted result in the excel file..?
With Regards,
Sangeetha.
|

Hi WhiteSky,
I could accomplish the sorting task through the following code:
sExcelFile = "F:\\PinListTested\\10-25\\aaa.xls";
sSql.Format("DRIVER={%s};DSN='';FIRSTROWHASNAMES=1;READONLY=FALSE;CREATE_DB=\"%s\";DBQ=%s", sDriver,sExcelFile,sExcelFile);
TRY
{
//database.Close();
// Open the database using the former created pseudo DSN
database.OpenEx(sSql,CDatabase::noOdbcDialog);
// Allocate the recordset
// Allocate the recordset
CRecordset record( &database );
// Build the SQL string
// Remember to name a section of data in the Excel sheet using
// "Insert->Names" to be able to work with the data like you would
// with a table in a "real" database. There may be more than one table
// contained in a worksheet.
sSql = "SELECT NET_NAME,DUT_PIN,TESTER_CHANNEL,TRACE_LENGTH "
"FROM Pin_List "
"ORDER BY DUT_PIN";
record.Open(CRecordset::forwardOnly,sSql);
sSql = "CREATE TABLE DUTPin_List (NET_NAME TEXT,DUT_PIN TEXT,TESTER_CHANNEL TEXT,TRACE_LENGTH float)";
database.ExecuteSQL(sSql);
while( !record.IsEOF() )
{
// Read the result line
CString Sql("INSERT INTO DUTPin_List (NET_NAME,DUT_PIN,TESTER_CHANNEL,TRACE_LENGTH) VALUES (");
record.GetFieldValue("NET_NAME",str1);
str1 = "'" + str1 + "',";
Sql += str1 ;
record.GetFieldValue("DUT_PIN",str1);
str1 = "'" + str1 + "',";
Sql += str1;
record.GetFieldValue("TESTER_CHANNEL",str1);
str1 = "'" + str1 + "',";
Sql += str1;
record.GetFieldValue("TRACE_LENGTH", str1);
str1 = str1 + ")";
Sql += str1;
database.ExecuteSQL(Sql);
// Skip to the next resultline
record.MoveNext();
}
record.Close();
database.Close();
}
CATCH(CDBException, e)
{
// A database exception occured. Pop out the details...
AfxMessageBox("Database error: " + e->m_strError);
}
END_CATCH;

Congratulation,
Finally you write sort.
|
|
|
|
|
Hi Whitesky,
I have posted the code in the previous reply. In that, the data is getting sorted. But am storing it in an another table. Because i didnt know to replace the contents in the "Pin_List" table, since it is linked to the record object.
With Regards,
Sangeetha.

Yes I saw you used of Create Table if your problem is for writting to excel file on the Codeproject you can see examples of it. (but I think you can use of another ways search on www.codeproject.com or www.codeguru.com or www.codersource.net In these sites you can see Database Folder that they have examples of excel)
|
|
|
|
|
Hi Whitesky,
I searched.. There are no such examples.. Please excuse me to say this.. Am looking for to coloring specified rows as well as to see the change in the same table instead of creating the second table.
With Regards,
Sangeetha.

You can create a windows service to check for the time. If the time in the system clock is what you need and it matches with what the user has scheduled, you can execute another application as you say.
Somethings seem HARD to do, until we know how to do them.

Could use Task Scheduler or...
If your app is always running, you could create a timer and check for a specific time in the OnTimer event, then use ShellExecute to run the other application.
